Nuts and Diabetes: Choosing the Right Fats for Better Health
By John Fisher
Eating nuts can be an excellent choice for individuals with diabetes, offering a variety of benefits such as stabilizing blood sugar levels and providing essential nutrients. However, the choice of nuts and how they are prepared can make a significant difference. Selecting nuts that aren’t roasted in vegetable oils is essential for managing diabetes, as the type of fat in nuts and oils can impact inflammation and blood sugar control.
The Impact of Different Fats
When considering fats, we generally classify them as “good” or “bad.” Good fats, found in foods like nuts, avocados, and olive oil, support cellular function, protect heart health, and may help manage blood sugar levels. Bad fats, on the other hand—often found in fried foods, heavily processed snacks, and vegetable oils used in roasting nuts—can increase inflammation, which has a direct link to insulin resistance and type 2 diabetes.
Polyunsaturated fats (PUFAs), present in some oils like vegetable, soybean, and corn oils, can be problematic for people with diabetes when consumed in high amounts. Dr. Chriss, a specialist in nutritional impacts on metabolic health, explained during our interview, “While nuts can offer fantastic nutrients, the PUFA-rich oils they’re often roasted in can drive inflammation and potentially worsen blood sugar management. It’s crucial for diabetics to check labels and avoid these oils.” In my own experience managing diabetes, I noticed an improvement in blood sugar stability when I switched to dry-roasted or raw nuts, steering clear of those cooked in inflammatory vegetable oils.
Nuts and Their Benefits for Diabetics
Many types of nuts are particularly beneficial for people with diabetes because they contain “good” fats, fiber, and protein, all of which help stabilize blood sugar levels and support satiety, reducing cravings for higher-carb snacks. Some top choices include:
Almonds: High in fiber and magnesium, almonds can improve insulin sensitivity, making them a great snack for people with diabetes. Magnesium has been linked to improved blood sugar control, and almonds provide it in abundance.
Walnuts: Known for their omega-3 fatty acids, walnuts support heart health, which is critical for diabetics, who face a higher risk of heart disease. Omega-3s also have anti-inflammatory properties, counteracting some of the inflammation associated with diabetes.
Macadamia Nuts: Lower in PUFA fats than many other nuts, macadamias offer monounsaturated fats, which are more stable and less likely to oxidize, minimizing inflammation risks. I’ve personally found macadamia nuts to be a satisfying, diabetes-friendly snack due to their low carbohydrate content and mild impact on blood sugar.
Pistachios: These nuts are high in fiber and offer a source of protein, both of which can help stabilize blood sugar after meals.
Avoiding Vegetable Oils
When selecting nuts, checking labels for added oils is essential. Many commercially roasted nuts are prepared with vegetable oils, including soybean, sunflower, or canola oil, which can be high in PUFAs. While PUFAs are necessary in small amounts, excessive consumption can lead to an imbalance, increasing inflammation and potentially affecting blood sugar control negatively.
Roasting nuts in oils also increases the risk of oxidation, especially when oils are exposed to high heat. Oxidized oils generate free radicals, which can contribute to chronic inflammation. Instead, look for raw or dry-roasted nuts without added oils, or try roasting them yourself at home with a touch of heart-healthy olive or avocado oil.
The Good Fat Advantage
Nuts offer a wealth of monounsaturated fats and some omega-3 fats, known to be anti-inflammatory and beneficial for managing diabetes. Incorporating a variety of nuts in moderation can support satiety and reduce blood sugar spikes, providing both nutritional benefits and flavor variety for those managing diabetes.
In my experience, opting for raw or dry-roasted nuts has made a tangible difference in managing my blood sugar levels. By making small adjustments like this, diabetics can enjoy the benefits of nuts without the added risks associated with vegetable oils and bad fats. As Dr. Chriss noted, “Choosing whole foods in their most natural form can make a significant impact on managing diabetes long-term.”
Note: I have been under the care of a functional medicine doctor to help manage my Type 2 diabetes through dietary changes. By eliminating inflammatory foods—such as grains, dairy, processed foods, and processed meats—I have lost 30 pounds and significantly reduced my A1C levels.
